Limp

Yesterday and today I've noticed Baxter has a limp, it seems to be sone form of stiffness as it stops once he's been moving for a while, is this worth a trip to the vets ?

Probs best get it checked out, Vinnie used to get it usually when stick or ball chasing.

If it's noticable then yes it is worth getting checked out, you don't want it worse if it's something that can be sorted easily now

Baxter went to the vets yesterday, she couldn't feel
Anything out of the ordinary but did say when she rubbed it he tilted his head like he was getting massage

Sounds positive I would say best thing is rest for a few days and see what happens though if it continues I would pop back

Maybe he's pulled a muscle, hope he recovers properly soon!

I agree, rest it up and see how it goes. If after that it doesn't get any better ask the vet to do some more investigation.
